DNA Changes That Affect Vitamin D Metabolism in Patients With Colorectal Cancer Receiving Vitamin D Supplements

ABSTRACT: RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This clinical trial is studying changes in DNA that affect vitamin D metabolism in patients with colorectal cancer receiving vitamin D supplements.

Vitamin E Supplements in Treating Patients Undergoing Surgery for Colorectal Cancer

Project description:RATIONALE: Vitamin E may help prevent the development of cancer. Studying samples of tissue from patients with colorectal cancer who receive Vitamin E before undergoing surgery in the laboratory may help doctors learn more about how Vitamin E changes biomarkers related to colorectal cancer. PURPOSE: This randomized early phase I trial is studying giving vitamin E supplements to see how it affects biomarkers in patients undergoing surgery for colorectal cancer.

Vitamin D Receptor regulation of hepatic energy metabolism in zebrafish

Project description:Vitamin D deficiency and mutations in Vitamin D Receptor (VDR) are associated with liver disease and obesity, but the functions of vitamin D signaling in metabolism are poorly understood. Though vitamin D signaling is best known for its functions in mineral homeostasis and skeleton calcification in terrestrial vertebrates, this is unlikely to be the evolutionary function of vitamin D signaling. We utilize tissue-specific genetic modulation of Vdr signaling to investigate the function of the vitamin D endocrine system in zebrafish. We find that hepatocyte Vdr regulates organismal response to nutritional cues and coordinates hepatic and organismal energy metabolism by balancing energy storage and tissue growth.

Vitamin B6 metabolism determines T cell anti-tumor responses

Project description:Targeting T cell metabolism is an established method of immunomodulation. Following activation, T cells engage distinct metabolic programs leading to the uptake and processing of nutrients that determine cell proliferation and differentiation. Redirection of T cell fate by modulation of these metabolic programs has been shown to boost or suppress immune responses in vitro and in vivo. Using publicly available T cell transcriptomic and proteomic datasets we identified vitamin B6-dependent transaminases as key metabolic enzymes driving T cell activation and differentiation. Inhibition of vitamin B6 metabolism using the pyridoxal 5’-phosphate (PLP) inhibitor, aminoxyacetic acid (AOA), suppresses CD8+ T cell proliferation and effector differentiation in a dose-dependent manner. We show that pyridoxal phosphate phosphatase (PDXP), a negative regulator of intracellular vitamin B6 levels, is under the control of the hypoxia-inducible transcription factor (HIF1), a central driver of T cell metabolism. Furthermore, by adoptive transfer of CD8 T cells into a C57BL/6 mouse melanoma model, we demonstrate the requirement for vitamin B6-dependent enzyme activity in mediating effective anti-tumor responses. Our findings show that vitamin B6 metabolism is required for CD8+ T cell proliferation and effector differentiation in vitro and in vivo. Targeting vitamin B6 metabolism may therefore serve as an immunodulatory strategy to improve anti-tumor immunotherapy.

Mouse iPS cells-derived 3D-retinas: Vehicle control- vs. 4-hydroxytamoxifen (4-OHT)-treated 3D-retinas w/o supplements

Project description:Transcriptional profiling of 3D-retinas differentiated from mouse iPS cells comparing vehicle control with 4-OHT-treated w/o supplements. 4-OHT is an inverse agonist of estrogen-related receptor beta (ERRÎ²), a rod-enriched transcription factor responsible for maintenance of rod photoreceptor cells and the treatment induces photoreceptor specific cell death in the 3D-retinas. Goal was to understand the mechanism of protective effects of representative ophthalmic supplements for treating the photoreceptor degeneration. 4-OHT w/o supplements-induced gene expression in the 3D-retinas was measured at DD 25 when the photoreceptor cells started to be degenerated. Four-condition experiment, vehicle control- vs. 5 ÂµM 4-OHT- vs. 5 ÂµM 4-OHT with 400 ÂµM vitamin E- vs. 5 ÂµM 4-OHT with 200 nM lutein-treated 3D-retinas. Biological replicates: each sample has 24 3D-retinas and 1replicate.

Scottish Colorectal Cancer Vitamin D Intervention Study (SCoViDS) [RNA-seq]

Project description:Controversy surrounds whether vitamin D reduces colorectal cancer (CRC) risk, and/or beneficially impacts on CRC survival. We sought to delineate the transcriptomic in vivo response of human colorectal epithelium to vitamin D supplementation, define inter-subject variability and develop a predictive biomarker of response consistent with anti-tumour effects. Methodology Blood and rectal normal mucosa (NM) were sampled (176 subjects) and correlation sought between circulating vitamin D (25-OHD) level and NM gene expression (HT12 microarray) in the observational study. Oral vitamin D (3200IU/day) supplements were administered to 50 participants in an intervention study. Blood and NM (sigmoidoscopic biopsy) were sampled after 12 weeks. Transcriptomic analysis (HT12 and RNAseq) of post-treatment biopsies assessed enrichment for candidate genes and GO processes prioritised in the observational study. We identified transcriptomic changes in rectum that are consistent with anti-tumour responses. We then sought blood biomarkers predicting this response using receiver-operator curves and calculation of C-statistic. An independent expression dataset (BEST-D trial) was then used to validate candidate blood biomarkers of vitamin D response.

Fiber and Fish Oil Supplements for the Prevention of Colorectal Cancer

Project description:This trial studies how fiber and fish oil supplements affect the metabolism and activities of colon cells in healthy individuals. Diet is an important risk factor for colorectal cancer, and several dietary components important in colorectal cancer prevention are modified by gut microbial metabolism. Giving fiber and fish oil supplements may inhibit the growth of gut cells and ultimately reduce risk of colorectal cancer.
